 # Edit Prediction
 
-Edit Prediction is Zed's mechanism for predicting the code you want to write through AI.
+Edit Prediction is Zed's LLM mechanism for predicting the code you want to write.
 Each keystroke sends a new request to the edit prediction provider, which returns individual or multi-line suggestions that can be quickly accepted by pressing `tab`.
 
-The default provider is [Zeta, a proprietary open source and open dataset model](https://huggingface.co/zed-industries/zeta), which [requires being signed into Zed](../authentication.md#what-features-require-signing-in).
-Alternatively, you can also use [other providers](#other-providers) like GitHub Copilot and Codestral.

 ## Configuring Zeta
 
-Zed's Edit Prediction was initially introduced via a banner on the title bar.
-Clicking on it would take you to a modal with a button ("Enable Edit Prediction") that sets `zed` as your `edit_prediction_provider`.
+To use Zeta, the only thing you need to do is [to sign in](../authentication.md#what-features-require-signing-in).
+After doing that, you should already see predictions as you type on your files.
 
-![Onboarding banner and modal](https://zed.dev/img/edit-prediction/docs.webp)
+You can confirm that Zeta is properly configured either by verifying whether you have the following code in your `settings.json`:
 
-But, if you haven't come across the banner, Zed's Edit Prediction is the default edit prediction provider and you should see it right away in your status bar.
+```json [settings]
+"features": {
+  "edit_prediction_provider": "zed"
+},
+```
+
+Or you can also look for a little Z icon in the right of your status bar at the bottom.
+
+### Pricing and Plans
+
+From just signing in, while in Zed's free plan, you get 2,000 Zeta-powered edit predictions per month.
+But you can get _**unlimited edit predictions**_ by upgrading to [the Pro plan](../ai/plans-and-usage.md).
+More information can be found in [Zed's pricing page](https://zed.dev/pricing).

+### Keybinding Example: Always Use Tab
+
+If you want to use `tab` to always accept edit predictions, you can use the following keybinding:
+
+```json [keymap]
+{
+  "context": "Editor && edit_prediction_conflict && showing_completions",
+  "bindings": {
+    "tab": "editor::AcceptEditPrediction"
+  }
+}
+```
+
+This will make `tab` work to accept edit predictions _even when_ you're also seeing language server completions.
+That means that you need to rely on `enter` for accepting the latter.

 ### Keybinding Example: Always Use Alt-Tab
 
-The keybinding example below causes `alt-tab` to always be used instead of sometimes using `tab`. You might want this in order to have just one keybinding to use for accepting edit predictions, since the behavior of `tab` varies based on context.
